To. all 'whom it ma/y conce/rn: I

y Be it known that 1GEORGE O'` SMITH, of Matteawan, in the county ofDutchess, and in the State of N ew York,have invented certain new anduseful Inrprovementsin Manufacture of Suctiou-Hose; and do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the aecompanyin g drawings,l and totheletters of reference marked thereon.

The natureof my invention consists in making suc tion-hose 'on hardrubber, or vgutta-percha rings, instead of on metal, `or wire rings, asheretoforegmade.

In order to enable others skilled in the artto which my inventionappertains, to make and use' the same, I will now proceed to describeits construction and operation, referring to the annexed drawings, whichform a part of this specification,- and in which- Figure 1 is across-section, and Figure 2 is a vertical section.

Therusual mode of making. suction-hose has been to have a series ofAmetal, or wire rings, on which the hose has been formed; but, by thismethod, the inner surface could never be made perfectly smooth,4 butwould always be more `or less irregular.

To obviatevths difficulty, I take a series of hardl rubber, orguttaf-pe'rcha rings, A A,'which may be vulcanized, so as to form aperfectly smooth surface on the inside.` g

By thus vulcanizingV the rings A A, they become perfectly solid, and thehose .B is then put on the outside Of said rings, in any of the knownand usual ways.

Besides the advantage of having a smooth inner surface, this hose willcost considerably less than any 'others heretofore made.

Having thus fully described my invention,

What I claim as new, and desire to secure by, Letters Patent, is-

Constructing suction-hose around a series of hard rubber, orguttafpercha rings, when said rings form the inside lining of the hose,and are connected, substantially in the manner and for the purposesherein set forth.

In testimony that I'claim the foregoing, I have hereunto set my hand,this 1st day of February, 1869. f

Q GEORGE o. SMITH.
